Abstract
Nanotechnology is of great importance in almost all modern day industries targeting high quality, efficiency and
market potential. The large interest in the nano-scale range is due to the fact that nanomaterials can have enhanced
properties, as compared to the same material with larger particle size. The modification of cellulose into different types
of micro- and nano-structures has been reported in literature. In papermaking, nanotechnological advances were
reported about a decade ago, though it could not be commercialized at a large scale. Nanofiber, nanofiller,
nanocomposites and nanoscale chemicals to be used in pulp and paper applications are in main focus. Because of the
wide abundance, renewable and environmentally benign nature, and outstanding mechanical properties of nano-based
cellulosic materials, great attention has been paid to their use in pulp and paper, and other industries. There are a few
challenges associated with their efficient use at a commercial scale, such as cost, lack of compatibility among materials
and knowledge gap. This review of recent work discusses the manufacturing, application and properties of different
nanoparticles and nano-based technological developments reported by researchers worldwide, related to cellulose and
paper manufacturing.
